Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
125 words
A METHOD OF MAKING AN ELECTRICALLY CONDUCTIVE COATING HAVING SURFACE RESISTIVITY IN THE RANGE FROM 10**-2 TO 10**11 OHMS PER SQUARE AND COMPRISING A METALCONTAINING SEMICONDUCTOR COMPOUND DISPERSED IN AN ELECTRICALLY INSULATING FILM-FORMING BINDER MATERIAL, SAID METHOD COMPRISING THE STEPS OF SOLUBILIZING SAID SEMICONDUCTOR COMPOUND BY MEANS OF A COMPLEXING AGENT THAT FORMS A SOLUBLE COMPLEX WITH THE SEMICONDUCTOR COMPOUND AND DISSOLVING THE SOLUBILIZED SEMICONDUCTOR COMPOUND IN A VOLATILE LIQUID SOLVENT, DISSOLVING SAID BINDER MATERIAL IN SAID SOLUTION, COATING THE SOLUTION ONTO A SUPPORT, EVAPORATING THE VOLATILE SOLVENT FROM THE COATED SOLUTION, AND REMOVING THE COMPLEXING AGENT FROM THE COATING TO LEAVE A RESIDUAL CONTINUOUS FILM OF SAID INSULATING BINDER MATERIAL HAVING DISPERSED THEREIN PARTICLES OF SIZE LESS THAN 0.1 MICRON OF SAID SEMICONDUCTOR COMPOUND.
